Title: Unload valve
Inventor: SEKIGUCHI MASUO
IPC: F16K17/04
Filed: 1981-11-19
Abstract: PURPOSE:To unload a fluid pressure pump and at the same time prevent a free motion of a load in case where a servo motor is not used in a variable capacity fluid pressure pump or a fixed capacity fluid pressure pump is used. CONSTITUTION:A switching valve 10 is pulled out in the arrow direction to isolate a room R5 from a room R4, so that the room R5 communicates with OR through a narrow flow path A5. Accordingly, a room R7 is opened to the air, and a spool valve 2 is pushed to the reight end by action of a left end spring 8. Since the connection between a room R1 and a room R2 is cut off in such circumstances, the pressurized fluid fed from a port CP1 of a fluid pressure pump P4 pushes up a check valve 3 to be supplied to a port CM1 of a fluid pressure motor MF. Thus, to pull the switching valve 10 in the arrow direction will cause the motor MF to drive regardless of an unload valve V.

Filed: 1993-06-28
Abstract: PURPOSE:To perform a positive confirmation of ignition and prevent error in ignition as well as over-heating at an ignition heater by a method wherein a temperature at a combustion cylinder is detected by a thermistor as a continuous electrical signal and a gradient of its temperature varying curve is calculated. CONSTITUTION:An ignition heater 9 is turned on at the time of ignition and after this state fuel is ignited to start its combustion, resulting in that an increasing temperature at a combustion cylinder 3 is detected by a thermistor 7 as a continuous electrical signal and at the same time this signal is transmitted to a control device 8. At the control device 8, a gradient at a temperature increasing curve of the combustion cylinder 3 is calculated in reference to the electrical signal. This calculation is carried out by a method in which a differentiation circuit is utilized for processing a signal obtained from the termistor 7 as its analog form. When either one condition in which a temperature at the combustion cylinder 3 detected in this way exceeds a predetermined temperature of the combustion cylinder or the other condition in which a gradient at a temperature increasing curve at the combustion cylinder 3 to be calculated exceeds a predetermined positive gradient is attained, it is judged that this state is in an ignition state. In addition, the ignition heater 9 is turned off when this judgement is carried out.

Title: Thin film electromagnetic transformer
Inventor: ISHIDA ARICHIKA
IPC: G06K19/06
Filed: 1988-07-25
Abstract: PURPOSE:To enable signals to be exchanged efficiently by forming a recess at which the end face of a magnetic substance layer is exposed in a position corresponding to the central part of each coil of the magnetic substance layer. CONSTITUTION:Recesses 15 and 15 are formed respectively at the central parts of individual coils 13 and 14, and since their side faces are the end faces of a magnetic film 12, magnetic fluxes flow out easily from the inner end faces of the recesses 15 and 15. In this case, if a magnetic pole arises in the direction along the face of the magnetic substance, the reverse magnetic field is much smaller as compared with the case that the magnetic pole arises in the direction crossing the face of the magnetic substance at right angles; therefore, the magnetic flux flows favorably. Accordingly, it can let flow the magnetic flux capable of obtaining signal strength sufficient for lead/light operation by a magnetic head. Hereby, the exchange of signals can be done efficiently.
